Arturo is a very sad polar bear, according to animal rights campaigners.

For months, the Mendoza Zoo outside of Buenos Aires, Argentina, has been criticized for keeping Arturo in hot, cramped conditions, reports The Winnipeg Sun.

Online video shows Arturo pacing his enclosure.

Despite efforts to have him moved to Assiniboine Park Conservancy in Winnipeg, Canada, Arturo is still at Mendoza Zoo.

The Canadian government requires at least three years of records about an animal before it can be brought into the country, and the Mendoza Zoo does have these records for Arturo, The Sun reports.

Online protesters are calling for Arturo's transfer, including a Change.org petition that has nearly 40,000 signatures. The conservancy offers a natural habitat for polar bears and "a better life is awaiting him," according to the petition.
